s a' vertical section on line f The parts being in the position shown in Fig. 2, in which the piston 6 occupies an upper position andthe casing is filled with a mass of tobacco equivalent to a certain num ber or portions of filler tobacco, introduced through the funnel 5, the manner of operation is as follows. Before the piston movesdown, a further portion of filler tobacco is fed into the casing, which will then be filled about casingp The piston'thenamoves down relatively to the casing to a certain level so as topress together the tobacco mass to a certain predetermined volume against the table 16. While .the piston remains in its said lower position, .the casing 1, 2,3, '4 moves upwards to the position shown in Fig. 5-carrying the cutter with it, which latter, however, during this movement remains in its swung out position,

so that from the tobacco mass formed by the tobacco portions pressed together apart, corresponding to that required for a roll, will ,be clearof'the casing at the'bottom and rest on the table; 'As soon as the position shown in Fig. 5.has been reached, the cutter .12 is swung inwards andcuts offthe said freeporshown in Fig. 2 'and the cut offfillertobacco will be rolled into a wrapper in. asuitable War-d direction; a

Then, the casing 1, 2, 3,4 ,and the pistonl6 return'to the position manner not shown.) the described operation being, then, repeated.* q 7 1 In'order th'a-t the tobacco shall notmake any 1 resistance when; moving 7 down through the casingor, tend "to raisev with the piston, after the portions have been pressed together, thecasing preferably widens in the downi @Theprinciple ofoperation of the embodi ment ofthe invention'above described is as follows: aftera certain number of portions, fornnstance, of fillerftobacco have been introduced and pressed together in the casing,

anadditional portion introducedfand, the piston-th enpresses together all portions to 3: r volume ,which is; always constant, from whicha-constant fraction in the present case l/.7,.,is cutoff.) If, then forieirample, the lastintroduced portionwere onlyof a normal portion while thejother portions, were however,practically normal, thetotal volume obtained will begfibz portions,from'which 1 /7th 1. 3., -6%, '1 /7=Q,965;ofa normal portion will becutofi. 5,, Ifone or more of the .firstportions were -"of somewhat greater-volume thanithe normal portion, the cut-off prart obviously, is ofga arepressed together and-so on.

volume, which still more nearly approaches the normal portion. As it is not possible in hitherto known devices for portioning filler tobacco forrolls to feed such small portions as are required for a single roll, without the 'such an equalization of theportions is obtained so, that all portions will, practically,

be equal in volume, involves considerable technicalv advantages. V I

When the invention is adapted for manufacturing rolls using long filler tobacco, the form of embodiment shown'i-n Fig. 6 is, preferably, used. 1

. In this case, the filler tobacco used for the rolls is fed fromabove the casing and between two-walls 26 applied-to the casing, which, if desired may in known manner form reciprocating gripping members feedingv the fillers.

*vVhenthe piston 6 moves down from the position shown inFigure 6, the tobacco portions placed between the walls 26 will by means of the piston be fed down into the casing. Then, subsequent operation-will be exactly analogous with that described with reference to Figs. 1 to 5.

Obviously, the invention may be carried out in. other manner than that described and shown. Thus, after a certain number, for instance, 7 portions have been reduced to a certainvolume, said volume may immediately be divided into seven equal parts, and, then seven new portions are brought together, before the next division is performed. I

This can, for instance, be effected in the following way Inthe position, shown in Fig. 2 thecasing is filled with the predetermined number, for instance, seven, portions. piston and knife are moved to the position shown in Fig. l, whereupon the piston moves down to a certain position so as to press together the seven portions to'a certain volume.

Then the casing-moves upwards to the position of Fig. 5, whereafter the uncovered'lower part of the mass is cut off by theknife and removed. Then the knife uncovers the outlet opening of the casing, whereuponthe piston by means-of a cam disc-or any other-known means, moves downafurtherto an extentcorresponding to the height ofthe cut-01f and rcmoved tobacco portion, so .as tomove the un- 'der surface ofthe remaining mass in-the cas ng 1nto, contact with the latch-16. "The knife 1s new again swung inward so as to cutoff the loweruncovered part of the mass. This operatlon s repeated until the casing is 7 empty. Finally the parts are brought to the original position, shown in Fig. 2, the'empty casing receiving agaln seven portions which Then the casing,

' alumnae lilurther, the, portions" fed into the casing may. be so large as to be each sufficient for,"for g a,

, of the caslng to close; thejsameymeansfor a 1 a J instance, two "rolls in which case' the tobacco Fig. 4: the greater portionsfe d being comportions, the combination-being preferably,

l volume'obtained, obviously, has to be divided into twiceas many'parts. as the number of por-.- tions which have been fed intothefcasing.

The parts are then moveclto the positionof pressed by the piston'to a certain volume, which is then cut into equal portions as de? I scribed above, the piston being moved further Y down after each cutting operation. to, an ex 7 i tent corresponding to the height-of the cut off v and removed tobacco portion. :When the cas-f' ing' is emptied, the parts are returnedto the position in Fig. 2. j I v The fed portions may also befsmaller'than the filler of a roll, for instance halfof it, and

in this casethe volume obtained has, obviously, to be divided into a; number of partswhichisjust half of the number of the smaller portions simultaneously brought together into the casing.

Preferably, the app aratus may be combined with a tobacco machine, aiso-called tobacco,

feeder, of the typewhich feeds the tobacco by.

such a one that the "portions fed fromthe tobacco feederwill automatically enter the casing. However, thetobacco portions, which are to be fed into the. casing,may'also be proportioned by other means or manually.

It is evldent that, 1n case of the casing containing a volume corresponding to a plurality V of portions, the piston has to be moved fur ther down after eachcutting operation to an I extent corresponding to the height of the cut off and-ren'ioved tobacco portion, so as to bring a p (the under surface of the remaining mass in the l casing into contact with the table ld; The

If the height of the portions tobei c'ut Oars;

predetermined, which obviously is the case in makingrolls of a certain 'siz'e, the movements 'ofthe casing away from-the table 16 always remain constant independent of thenuinber 1 and size of the portions fed into the'casing Y cutting operation through. a distance can responding to'the height of thecut-oflf' portions, so that, before the ne'xt'cutting opera- Itiontakes place, theremaining mass in the; v casing will alwaysiabutagainstf the table 16. vWhat we claim asfnew and desire to secu're '66 by Letters Patent'isf:
